The actress told E! that eating wasn't really possible. "I think I may be trying to get sympathy a bit there. I'm being a bit over the top," she prefaced. "When [the corset] was on, we would be on continuous days so we wouldn't stop for lunch or a lovely tea like this — you'd be sort of eating on the move. In that case, I couldn't untie the corset. So if you ate food it didn't really digest properly and I'd be burping all afternoon in [Richard Madden]'s face, and it was just really sort of unpleasant. I'd have soup so that I could still eat but it wouldn't get stuck."

Uh, no wonder Cinderella leaves that ball in a hurry. She doesn't want to burp in Prince Charming's face!

OK, aside from how uncomfortable that sounds, what's even more unpleasant is that that's our society's ideal image of beauty: A girl whose waist is so small she literally can't eat anything but liquid calories.

Thankfully, James recognizes this is completely unrealistic and encourages younger girls to have a healthier outlook.

"For girls growing up, sometimes I think they get the wrong idea for what women should look like," the actress said. "And I think it's so important to be healthy and confident and natural. And not put too much stress on trying to be thin — I don't get the thin, thin thing at all. I'm actually finding it really hard not to eat right now."
